Why can't they ever make the figures that I want?

So I was browsing the DC Direct site, looking at the pretty pictures of the upcoming Justice League International line, and noticed this in the description of one of the Series 2 figures:

...these four characters round out the original incarnation of the Justice League International!

I am assuming that the words "round out" mean that these two waves are it for this line.

And here I'd been really hoping for a JLI Elongated Man and Sue Dibny. Darn it.
